Alstroemeria named Nevada

ABSTRACT

A new and distinctive alstroemeria cultivar particularly distinguished by its medium-size flowers having generally an ivory-white flower color, leaves and internodes being shorter than common varieties, pedicels having a horizontal setting on the main stem and high productivity.

Background of the New Plant

This alstroemeria cultivar originated as a hybrid seedling produced in my nursery at Hillegom, The Netherlands by my crossing of two plants, hereinafter identified, selected from a field of various alstroemeria varieties maintained at my nursery gor breeding purposes. This particular seedling was selected from those produced by the said hybrid because of the very unusual flower coloration on a plant having abundant foliage and very favorable growth characteristics. This selected seedling was propagated by me at Hillegom by dividing its roots with very satisfactory results and thereafter this selected plan was propagated through several successive generations in the same manner which demonstrated conclusively that the novel characteristics of the originally selected seedling would be maintained from gneration to generation and its homogeneity would be firmly established.

Nevada is similar to Alstroemeria named Stalibla (U.S. Plant Pat. No. 7,886) and Alstroemeria named Stablaco (U.S. Plant Pat. No. 4,930). Below in a tabular format, is a side-by-side comparison of the varieties.
